Extract text from CDX files
To convert your CDX file to another format, you need Microsoft Visual FoxPro or other Database software.
To convert other file formats to the "Compound Index File" file type, you need software like Microsoft Visual FoxPro or a similar tool.
The .CDX extension is shared by several distinct file formats, creating frequent confusion for users. The most common variation is the Compound Index File used by the discontinued Microsoft Visual FoxPro. These files function as an external index for DBF database files to speed up searching and sorting. Since FoxPro was retired in 2007, these files represent a significant legacy data trap; they cannot be opened as standalone documents and require the original .DBF to be useful. Converting the underlying database to CSV, SQL, or XLSX is often necessary for modern data migration.
The second most prevalent use is the ChemDraw Exchange format by Revvity Signals (formerly PerkinElmer). These are vector-based files used by chemists to represent molecular structures. The primary difficulty here is the proprietary nature of the software; viewing a .CDX file requires an expensive license or specific academic software. For publication, collaboration, or web use, these files must be converted to PDF (for documents), PNG (for web), or standard chemical formats like MOL or SDF.
Other less common variations include ConceptDraw XML diagrams and Web Archive index files.
Convert.Guru analyzes your CDX file, detects the exact format, and lets you read the text inside.
Users also converted CDXML, CDAX, DBF, CDX63, GZ, RCDX, CDDX, PDF, FPT, CDXX, ZIP, KDX and CDR files.
If you want to convert CDX file to PDB, JPG, PDF, MOL, EXE, CSV, JSON, XML, YAML, YML, TOML or INI, you can use Microsoft Visual FoxPro or similar software from the "Database Indexing & Chemical Drawing" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to CDX, try Microsoft Visual FoxPro or another comparable tool in the "Database Indexing & Chemical Drawing" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CDX converter.
